Description

Technical Field

[0001] This utility model relates to the field of extrusion molding machine technology, and in particular to a steel-plastic granule extrusion molding machine. Background Technology

[0002] Steel-plastic profiles have the characteristics of good sound insulation, good air tightness, aging resistance, non-corrosiveness, good water tightness, impact resistance, good fire resistance, and good thermal insulation. During the use of existing steel-plastic profile granule extrusion equipment, the continuous accumulation of unmelted impurities in the raw materials can easily cause the die head to become clogged, affecting the production of steel-plastic profiles. Therefore, it is necessary to clean or replace the die head.

[0003] Existing technologies, such as Chinese Patent Publication No. CN217670961U, disclose an extrusion device for plastic steel profile granules, including a machine body, a fixed plate, a die head, a groove, a slider, a slot, and a limiting mechanism. During installation, the die head is connected to the machine body, and a positioning block positions the die head. Pulling the connecting rod moves the locking rod, pushing the slider to engage with the groove, and then with the die head. Releasing the connecting rod allows the locking rod to engage with the slot. A spring stabilizes the engagement between the locking rod and the slot, thereby stabilizing the engagement between the slider and the groove, and ultimately stabilizing the engagement between the slider and the die head. The engagement between the slider and the groove prevents the die head from rotating, and the engagement between the slider and the die head prevents movement, thus stabilizing the engagement between the die head and the machine body. For cleaning the die head, pulling the connecting rod separates the locking rod from the slot, and moving the slider separates the slider from the die head, thus separating the die head from the machine body. The device is simple to operate and facilitates cleaning of the die head. However, this utility model requires the complete removal of the machine head for cleaning, which is inconvenient.

[0004] To address the issue of inconvenient cleaning and disassembly of the die head in steel-plastic granule extrusion molding machines, the existing equipment typically uses flanges to fix the die head to the machine body, requiring the removal of multiple sets of bolts. This makes cleaning or replacing the die head quite inconvenient, so improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that it is inconvenient to clean and disassemble the die head in the existing steel-plastic granule extrusion molding machine, and to propose a steel-plastic granule extrusion molding machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a steel-plastic granule extrusion molding machine, comprising a machine body, a fixed plate, a die head, a feeding hopper, and a loading and unloading mechanism. The fixed plate is fixedly connected to the surface of the machine body, the die head is disposed on the surface of the fixed plate, the feeding hopper is fixedly connected to the surface of the machine body, and the loading and unloading mechanism is disposed on the surface of the fixed plate. The loading and unloading mechanism includes a limiting rod, which is fixedly connected to the surface of the fixed plate. A movable disc is slidably connected to the surface of the limiting rod, and an insert rod is fixedly connected to the surface of the movable disc. The insert rod is slidably connected to the inner wall of the fixed plate, and a spring is sleeved and connected to the surface of the insert rod. One end of the spring is fixedly connected to the surface of the movable disc, and the other end of the spring is fixedly connected to the surface of the fixed plate. An installation ring is fixedly connected to the surface of the die head, and the insert rod is slidably connected to the inner wall of the installation ring. A locking block is fixedly connected to the surface of the insert rod, and a locking groove is formed on the surface of the installation ring. The locking block is locked and connected to the surface of the locking groove. An L-shaped plate is fixedly connected to the surface of the fixed plate, and the L-shaped plate cooperates with the installation ring.

[0007] Furthermore, a screw hole is provided on the surface of the insertion rod, and a screw rod is threadedly connected to the surface of the screw hole. A turntable is fixedly connected to the surface of the screw rod.

[0008] Furthermore, a connecting rod is fixedly connected to the surface of the turntable, and a limiting plate is fixedly connected to the surface of the connecting rod. The limiting plate is slidably connected to the surface of the insert rod.

[0009] Furthermore, there are two sets of limit rods arranged symmetrically, multiple sets of locking blocks evenly distributed around the circumference, and multiple sets of locking slots evenly distributed around the circumference.

[0010] Furthermore, an adjustment mechanism is provided on the surface of the feed hopper. The adjustment mechanism includes a motor, which is fixedly installed on the surface of the feed hopper. The output end of the motor is fixedly connected to a screw rod, which is rotatably connected to the inner wall of the feed hopper.

[0011] Furthermore, a movable block is threadedly connected to the surface of the screw two, a connecting rod is rotatably connected to the surface of the movable block, a trapezoidal plate is rotatably connected to the end of the connecting rod away from the movable block, and a groove is opened on the surface of the feed hopper, with the trapezoidal plate slidingly connected to the surface of the groove.

[0012] Furthermore, there are two sets of connecting rods, trapezoidal plates, and slides. The surface of the slide is provided with a relief groove, and an auxiliary roller is rotatably connected to the surface of the relief groove.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up a loading and unloading mechanism, when only the machine head needs to be cleaned, the movable disc is pressed along the limit rod, and the spring is tightened, causing the insert rod to move accordingly, thereby causing the locking block to disengage from the slot. At this time, the mounting ring can rotate freely. Hold the mounting ring and rotate it half a turn along the insert rod to disengage the inner side of the machine head from the fixing plate. Then release the movable disc, and the insert rod returns to its original position under the spring's rebound. The locking block continues to lock the slot, fixing the machine head. At this time, the inside and outside of the machine head can be cleaned directly without completely disassembling the machine head. After cleaning, repeat the above operation to reset the machine head. However, if the machine head needs to be removed for replacement, simply repeat the above operation. After rotating the machine head half a turn, rotate the turntable to remove the screw from the screw hole. Then, pull the machine head out along the insertion rod. Insert the new machine head into the insertion rod and rotate it to the initial position. Then, rotate the turntable in the opposite direction to move the screw along the screw hole. The connecting rod, limit plate, and L-shaped plate can limit the displacement of the machine head along the insertion rod axial direction. By setting up the loading and unloading mechanism, the machine head can be loaded and unloaded quickly, and it can also be cleaned without completely removing the machine head, which effectively improves the convenience of the equipment.

[0015] 2. In this utility model, by setting an adjustment mechanism, the motor is started to drive the screw to rotate, causing the movable block to move up and down. The connecting rod drives the two sets of trapezoidal plates to move towards each other or away from each other along the slide, thereby realizing the adjustment of the size of the feed hopper opening, thereby adjusting the feed amount and feed speed. The auxiliary roller set can make the movement of the trapezoidal plates smoother. By setting an adjustment mechanism, the feed amount and feed speed can be easily adjusted so as to make adaptive adjustments according to different needs, thus effectively improving the applicability of the equipment.

[0024] The specific configuration and function of its loading and unloading mechanism 5 and adjusting mechanism 6 will be explained below.

[0025] In this implementation scheme: the loading and unloading mechanism 5 includes a limiting rod 501, which is fixedly connected to the surface of the fixed plate 2. A movable disc 502 is slidably connected to the surface of the limiting rod 501. An insert rod 503 is fixedly connected to the surface of the movable disc 502. The insert rod 503 is slidably connected to the inner wall of the fixed plate 2. A spring 504 is sleeved and connected to the surface of the insert rod 503.

The L-shaped plate 508 cooperates with the installation ring 505.

[0026] The effects achieved by the above components are as follows: the limiting rod 501 is set to prevent the insertion rod 503 and the movable plate 502 from rotating; the movable plate 502 is set to facilitate the movement of the insertion rod 503; the insertion rod 503 and the mounting ring 505 are set to facilitate the rotation of the machine head 3; the spring 504 is set to both lock the locking block 506 into the locking groove 507 to prevent the machine head 3 from rotating arbitrarily during operation, and to facilitate the reset of the insertion rod 503 by utilizing its rebound effect; the locking block 506 and the locking groove 507 are set to facilitate the fixation of the machine head 3 and prevent it from rotating arbitrarily; and the L-shaped plate 508 is set to prevent the machine head 3 from displacing along the axial direction of the insertion rod 503 during operation.

[0027] Specifically, the surface of the insertion rod 503 is provided with a screw hole 509, the surface of the screw hole 509 is threaded with a screw rod 510, and the surface of the screw rod 510 is fixedly connected with a turntable 511.

[0028] The effects achieved by the above components are as follows: the screw hole 509 and the screw 510 are provided so that when the screw 510 is disengaged from the screw hole 509, the machine head 3 can be removed from the insert rod 503 for easy replacement; the turntable 511 is provided to facilitate the rotation of the screw 510.

[0029] Specifically, a connecting rod 512 is fixedly connected to the surface of the turntable 511, and a limiting plate 513 is fixedly connected to the surface of the connecting rod 512. The limiting plate 513 is slidably connected to the surface of the insertion rod 503.

[0030] The effect achieved by the above components is as follows: the connecting rod 512 and the limiting plate 513 are designed to both cooperate with the L-shaped plate 508 to limit the displacement of the machine head 3 along the axial direction of the insertion rod 503 during operation, and to prevent the machine head 3 from moving arbitrarily along the axial direction of the insertion rod 503 when cleaning after rotating the machine head 3 half a turn.

[0031] Specifically, there are two sets of limit rods 501 arranged symmetrically, multiple sets of locking blocks 506 evenly distributed around the circumference, and multiple sets of locking slots 507 evenly distributed around the circumference.

[0032] The effects achieved by the above components are as follows: setting two sets of limit rods 501 is to increase the stability of the movable plate 502 when it moves; setting multiple sets of locking blocks 506 and locking slots 507 is to allow the machine head 3 to be fixed at multiple angles, which facilitates cleaning of the machine head 3.

[0033] Specifically, the surface of the feed hopper 4 is provided with an adjustment mechanism 6, which includes a motor 61. The motor 61 is fixedly installed on the surface of the feed hopper 4, and the output end of the motor 61 is fixedly connected to a screw 62. The screw 62 is rotatably connected to the inner wall of the feed hopper 4.

[0034] The effect achieved by the above components is that the motor 61 and the screw 62 are set so that when the motor 61 drives the screw 62 to rotate, the movable block 63 moves up and down.

[0035] Specifically, the surface of the screw 62 is threaded with a movable block 63, the surface of the movable block 63 is rotatably connected with a connecting rod 64, the end of the connecting rod 64 away from the movable block 63 is rotatably connected with a trapezoidal plate 65, the surface of the feed hopper 4 is provided with a sliding groove 66, and the surface of the trapezoidal plate 65 is slidably connected to the surface of the sliding groove 66.

[0036] The effect achieved by the above components is as follows: during the up-and-down movement of the movable block 63, the connecting rod 64 can drive the two sets of trapezoidal plates 65 to move towards each other or away from each other along the slide 66, thereby adjusting the size of the opening of the feed hopper 4. The trapezoidal plates 65 are set to facilitate the entry of materials into the feed hopper 4.

[0037] Specifically, there are two sets of connecting rod 64, trapezoidal plate 65 and slide groove 66. The surface of slide groove 66 is provided with relief groove 67, and auxiliary roller 68 is rotatably connected to the surface of relief groove 67.

[0038] The effect achieved by the above components is as follows: the clearance groove 67 is provided to facilitate the placement of the auxiliary roller 68, and the auxiliary roller 68 is provided to assist the movement of the trapezoidal plate 65, making it slide more smoothly along the slide groove 66 and avoiding jamming.

[0039] Working principle: By setting up the loading and unloading mechanism 5, when only the machine head 3 needs to be cleaned, press the movable plate 502 along the limit rod 501, and the spring 504 is pressed, causing the insertion rod 503 to move accordingly, thereby causing the locking block 506 to disengage from the slot 507. At this time, the mounting ring 505 can rotate freely. Hold the mounting ring 505 and rotate it half a turn along the insertion rod 503 to make the inner side of the machine head 3 disengage from the fixing plate 2. Then release the movable plate 502, and the insertion rod 503 returns to its original position under the rebound action of the spring 504. The locking block 506 continues to lock the slot 507, thus fixing the machine head 3. At this time, the inside and outside of the machine head 3 can be cleaned directly without completely removing the machine head 3. After cleaning, repeat the above operation to reset the machine head 3. If the machine head 3 needs to be removed for replacement, simply repeat the above operation, rotate the machine head 3 half a turn, rotate the turntable 511 to remove the screw 510 from the screw hole 509, and then pull out the machine head 3 along the insertion rod 503. Insert the new machine head 3 into the insertion rod 503 and rotate it to the initial position. Then, rotate the turntable 511 in the opposite direction to move the screw 510 along the direction of the screw hole 509. The connecting rod 512, the limiting plate 513, and the L-shaped plate 508 can be used to limit the displacement of the machine head 3 along the axial direction of the insertion rod 503. By setting the loading and unloading mechanism 5, the machine head 3 can be loaded and unloaded quickly, and it can also be cleaned without completely removing the machine head 3, which effectively improves the convenience of the equipment.

[0040] Furthermore, by setting an adjustment mechanism 6, the motor 61 is started to drive the screw 62 to rotate, causing the movable block 63 to move up and down. The connecting rod 64 drives the two sets of trapezoidal plates 65 to move towards each other or away from each other along the slide 66, thereby adjusting the size of the opening of the feed hopper 4, and thus adjusting the feed amount and feed speed. The auxiliary roller 68 set up can make the movement of the trapezoidal plates 65 smoother. By setting up the adjustment mechanism 6, the feed amount and feed speed can be easily adjusted so as to make adaptive adjustments according to different needs, thus effectively improving the applicability of the equipment.
